Structured Workflow MCP

🚀 Structured Workflow MCP Server

An MCP server that enforces disciplined programming practices by requiring AI assistants to audit their work and produce verified outputs at each phase of development.

Why I Built This

TLDR: I got tired of repeating "inventory and audit first" across every AI platform and prompt, so I built an MCP server that automatically enforces this disciplined approach. It forces AI to think systematically and follow structured phases instead of jumping straight into code changes.

I built an MCP server that fits into my programming workflow and thinking process. It's available via npx, and you can download it locally if you prefer.

Essentially, when working with AI on refactoring tasks for a larger project, I faced issues like the AI missing key elements, creating duplicates, leaving orphaned code, or making syntax errors in tests. I realized the AI needed to perform an audit and inventory before implementation, along with a lint-iterate-lint phase. After trying rules with limited success and prompting with better results, I decided to create an MCP server that forces the AI to work through problems in phases. It has various workflow styles, and I'm open to ideas and improvements.

Features

• Enforced Workflow Phases: AI must complete specific phases in order (setup, audit, analysis, planning, implementation, testing, etc.).
• Mandatory Output Artifacts: Each phase requires structured documentation or verified outputs before proceeding.
• Multiple Workflow Types:
  • Refactor workflows for code improvement.
  • Feature development with integrated testing.
  • Test-focused workflows for coverage improvement.
  • Test-driven development (TDD) cycles.
  • Custom workflows for specialized needs.
• Output Verification: The server validates that outputs contain meaningful content and proper structure.
• Session State Management: Tracks progress and prevents skipping phases.

How It Works

Here's how the AI moves through a structured workflow:

    style C fill:#fff3e0
    style D fill:#e8f5e8
    style E fill:#fff9c4
    style H fill:#e8f5e8

What happens at each step:

1. Start Workflow: AI calls a workflow tool (refactor_workflow, create_feature_workflow, etc.).
2. AI Gets Phase Guidance: Server provides specific instructions for the current phase (audit, analyze, implement, etc.).
3. Create Phase Output: AI works through the phase and creates documentation/artifacts.
4. Auto-Save: Files are automatically saved with numbered naming in task directories.
5. Phase Validation: Server validates outputs meet requirements before proceeding.
6. Next Phase: Process repeats until workflow is complete.

One benefit of this breakdown is that the AI agent receives instruction sets relevant to the current phase, preventing it from getting lost in the entire workflow and focusing on the current phase. An interesting article on this can be read here: LLMs Get Lost In Multi-Turn Conversation.

Workflow Output

AI-Generated Documentation

The server suggests numbered workflow files as you progress through phases. The AI assistant handles the actual file creation using its own tools:

workflows/
├── your-task-name/
│   ├── 01-audit-inventory-2025-01-04.md
│   ├── 02-compare-analyze-2025-01-04.json
│   ├── 03-question-determine-2025-01-04.md

Workflow Architecture

• File Handling: The server provides suggested paths and formats but does not directly write files. Instead, it instructs the AI assistant to create these files using its own file system access.
• Consistent Naming: Files follow a standardized naming convention with phase numbers, names, and timestamps.
• Environment Independence: The architecture works across any environment where the AI has appropriate file system permissions.
• Graceful Degradation: If the AI is unable to create files, the workflow continues in memory-only mode - your progress isn't interrupted.

Installation

Quick Start (Recommended) - Zero Installation

Add to your AI assistant config - Uses npx automatically:

💡 Note: I recommend using @latest to ensure you always get the newest features and fixes. Without @latest, npx may cache older versions.

VS Code / Cursor / Windsurf - Add to your MCP settings:

{
  "mcp": {
    "servers": {
      "structured-workflow": {
        "command": "npx",
        "args": ["structured-workflow-mcp@latest"],
        "env": {}
      }
    }
  }
}

Claude Desktop - Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "structured-workflow": {
      "command": "npx",
      "args": ["structured-workflow-mcp@latest"],
      "env": {}
    }
  }
}

Global Installation (Optional)

You can install globally on your machine using NPM:

npm install -g structured-workflow-mcp

Then use in your AI assistant config:

{
  "mcp": {
    "servers": {
      "structured-workflow": {
        "command": "structured-workflow-mcp",
        "args": [],
        "env": {}
      }
    }
  }
}

With custom output directory:

{
  "mcp": {
    "servers": {
      "structured-workflow": {
        "command": "structured-workflow-mcp",
        "args": ["--output-dir", "/home/user/workflow-outputs"],
        "env": {}
      }
    }
  }
}

Auto-Install via Smithery

Smithery provides a number of ways to install directly into your apps including this way for Claude Desktop:

npx -y @smithery/cli install structured-workflow-mcp --client claude

Manual Installation

For developers, you can clone the repository and build it locally:

git clone https://github.com/kingdomseed/structured-workflow-mcp
cd structured-workflow-mcp
npm install && npm run build

Usage

Once configured in your AI assistant, start with these workflow tools:

• mcp__structured-workflow__build_custom_workflow - Create custom workflows.
• mcp__structured-workflow__refactor_workflow - Structured refactoring.
• mcp__structured-workflow__create_feature_workflow - Feature development.
• mcp__structured-workflow__test_workflow - Test coverage workflows.

Example Output Artifacts

The server enforces that AI produces structured outputs like these:

AUDIT_INVENTORY Phase Output:

{
  "filesAnalyzed": ["lib/auth/user_service.dart", "lib/auth/auth_middleware.dart"],
  "dependencies": {
    "providers": ["userProvider", "authStateProvider"],
    "models": ["User", "AuthToken"]
  },
  "issues": [
    "Single Responsibility Principle violation - handles too many concerns",
    "File approaching 366 lines - recommended to keep widgets smaller"
  ],
  "changesList": [
    {
      "action": "CREATE",
      "file": "lib/auth/components/auth_form.dart",
      "description": "Extract authentication form logic",
      "justification": "Component focused on form validation only"
    }
  ]
}

COMPARE_ANALYZE Phase Output:

{
  "approaches": [
    {
      "name": "Incremental Component Extraction",
      "complexity": "Medium",
      "risk": "Low", 
      "timeEstimate": "30-45 minutes"
    }
  ],
  "recommendation": "Incremental Component Extraction",
  "justification": "Provides best balance of benefits vs. risk",
  "selectedImplementationOrder": [
    "1. Extract form component (lowest risk)",
    "2. Create validation service",
    "3. Refactor main view"
  ]
}

Each phase requires documented analysis and planning before the AI can proceed to implementation.

Tools

Workflow Entry Points

• refactor_workflow - Start a structured refactoring process with required analysis and planning phases.
• create_feature_workflow - Develop new features with integrated testing and documentation requirements.
• test_workflow - Add test coverage with mandatory analysis of what needs testing.
• tdd_workflow - Implement Test-Driven Development with enforced Red-Green-Refactor cycles.
• build_custom_workflow - Create workflows with custom phases and validation requirements.

Phase Guidance Tools

• audit_inventory_guidance - Forces thorough code analysis and change cataloging.
• compare_analyze_guidance - Requires evaluation of multiple approaches with pros/cons.
• question_determine_guidance - Mandates clarification and finalized planning.
• phase_output - Validates and records structured outputs from each phase.
• workflow_status - Check current progress and validation state.

Usage

The server enforces structured workflows through mandatory phases. Each workflow type has different phase requirements:

• Refactor Workflow: AUDIT_INVENTORY → COMPARE_ANALYZE → QUESTION_DETERMINE → WRITE_OR_REFACTOR → LINT → ITERATE → PRESENT.
• Feature Workflow: PLANNING → QUESTION_DETERMINE → WRITE_OR_REFACTOR → TEST → LINT → ITERATE → PRESENT.
• Test Workflow: AUDIT_INVENTORY → QUESTION_DETERMINE → WRITE_OR_REFACTOR → TEST → ITERATE → PRESENT.
• TDD Workflow: PLANNING → WRITE_OR_REFACTOR → TEST → (Red-Green-Refactor cycles) → LINT → PRESENT.

Input Validation

The server requires:

• task (string): Description of what you want to accomplish.
• outputArtifacts (array): Structured documentation for each completed phase.

Output Validation

Each phase completion is validated for:

• Meaningful content length (minimum 10 characters).
• Valid JSON format for structured outputs.
• Phase-specific content requirements.
• Proper documentation of decisions and analysis.

Safety Rule

Files must be read before modification. This prevents accidental data loss and ensures informed changes.

Development

npm run dev      # TypeScript compiler in watch mode  
npm run lint     # Run linter
npm run typecheck # Type checking
npm test         # Run tests

How It Works

1. AI starts a workflow using one of the entry point tools.
2. Server creates a session and tracks phase progression.
3. Each phase requires specific outputs before proceeding.
4. The phase_output tool validates artifacts have meaningful content.
5. AI cannot skip phases or claim completion without verified outputs.
6. Session state prevents circumventing the structured approach.

Testing the MCP Server

You can quickly try out the Structured Workflow MCP server using the test prompts and helper scripts included in this repository.

1. Build the server (if you haven't already):

   npm run build
   

2. Start the server:

   node dist/index.js
   

3. Open the test prompt docs/test_prompt/mcp_server_test_prompt.md in your preferred MCP-compatible AI client and paste the contents.
4. Alternatively, open the sample project located in refactor-test/ for an end-to-end refactor workflow demo. Follow the steps in its README.md to run and observe the structured workflow in action.
5. Watch the AI progress through each phase and verify the structured outputs produced.

Sample Prompts

The docs/sample_prompts directory contains several ready-to-use prompts illustrating typical workflows:

• feature_workflow_prompt.md
• refactor_workflow_prompt.md
• test_workflow_prompt.md
• tdd_workflow_prompt.md
• custom_workflow_prompt.md

Use these as a starting point and adapt them to your projects.

Building

npm install
npm run build

The server uses TypeScript with the @modelcontextprotocol/sdk and runs locally via stdio transport.
